1. Preparation before work: 1. According to the thickness of the weldment to select the structure of the form, according to the strength to choose the form of the joint. 2. According to the thickness of the weldment to choose the electrode diameter and welding current. • Adjust the welding current on the welding machine. 3. There are two kinds of arc-striking methods: the tapping method and the drawing method. Everyone chooses the arc-striking method according to their own habits.
2 Safe operation at work 1. Wear welding shoes during welding and do not barefoot. 2. Welded gloves must be worn when welding, use protective cover. 3. During the operation, the welding rod must move along the welding direction. The speed of the movement should be properly grasped so fast that the welding cannot be conducted. If it is too slow, the temperature of the sewing seam will be too high, and welding defects will occur. 4 arc length should not be too long and too short.
Second, the safe use of the grinder:
1. Check that the fastening bolts of the grinding wheel are tight.
2. Whether the grinding machine has impurities, if it should be cleaned.
3. When working, slowly put the parts into the surface of the grinding wheel. Don't be too fast. Especially when parts and grinding wheels are to be joined, care should be taken.
4. The operator should stand outside the plane of rotation of the grinding wheel to prevent the wheel from accidents due to poor quality.
5. Operators should wear work clothes and work caps and gloves.
6. After being ground by the grinder, the parts will be hot and should be handled carefully.
Third, the battery maintenance and safe use
1. The dust and dirt on the battery should be promptly removed, and the oxides on the electric pile and the wire connector must be removed.
2. Normally, the insulation shield on the battery should be properly covered. During maintenance, it is forbidden to place tools or other metal conductors on the battery to avoid short circuit.
3. Always check the height of the electrolyte surface. If you find that the liquid level drops, you should add distilled water.
4. When starting electric, the starting time must not exceed 15 seconds.
5. Do not use interchangeable batteries of different capacities.
6. Pay attention to the working condition of the ammeter while working. If any problem is found, check it immediately.
7. Please pay attention to the polarity when installing and connecting the battery. Do not connect wrongly.
Fourth, the safe use of manual drilling
1. Check before operation 1. Before using the hand drill, you must check whether the current voltage is the same as the voltage of the hand drill, especially if the hand drill is imported, if it is not the same, it must not be connected to the power supply.
2. Check that the hand drill casing is grounded (protection line).
3. The size of the hand drill bit may not exceed the standard of the hand drill. If the drill bit is too large, the hand drill will be burned due to overload.
4. The drill must be sharp.
2. Safe operation at work 1. After the above checks, first observe if the drill is operating normally for a moment. 2. When drilling, to prevent overload, do not press too hard. • Slowly exit the drill bit when the load suddenly decreases. 3. When the drill suddenly stops, switch off the switch immediately, cut off the power supply and find out the reason. Must not be opened again. 4. The opponent's electric drill must be maintained, especially for the commutator carbon brush should be cleaned or replaced in order to extend the service life.
Fifth, the safe use of lathes
1. When installing blank parts on the lathe, it should be installed after the lathe stops.
2. The three-card fastening bolts must be fastened.
3. When the turning tool is installed, the turning tool should be extended properly.
4. The amount of cutters during turning should not be too large to prevent the deformation of the parts and affect the precision or lathe overload and damage the parts of the lathe.
5. When lesbians turn parts, they must wear a cap to prevent accidental hair getting involved in the lathe.
6. When turning, the operator should not stand on the same plane with the same turning to prevent the iron scraps from splashing into the eyes and causing accidents. It should be offset a bit from the turning plane.
7. When unloading parts should pay attention to parts after turning parts surface temperature increases to prevent scalding.
The dimensions is: Width:500mm*Length:1800m*Thickness:25um.
The 3Fagri Silage Wrap has been manufactured by Zibo Maoyang Industry and Trading CO., LTD in China, using advanced multi-layer co-extrusion blown film technology and equipment.
The silage wrap is a high performance multi-layer blown co-extruded Agricultural Stretch Film, strong and reliable.
